NON REFILLABLE BOTTLE.

To all whom it may concern.'

Be it known that we, OSCAR L. WEIGERT, GEORGE G. GRAHAM, and GEORGE F. ULL- RIoH, citizens of the United States, residing at Missoula, in the county of Missoula and State of Montana, have invented certain new and useful Improvements in Non-Relillable Bottles, of which the following is a speciiieation.

This invention relates to bottles provided with means whereby, after having been once lilled, they cannot be refilled, the invention consisting broadly in the provision of a plurality of valve seats in the neck of the bottle, and `the association with each valve seat of a valve therefor, one of said valves of a solid and relatively heavy character so that when the bottle is in its ordinary position, said valve shall be seated and close the entrance "of the bottle, while the other valve is hollow,

and therefore when the bottle is inverted for the unauthorized introduction of liquid, the valve will, by its buoyancy, rise to its seat, thereby closing the bottle against the introduction of said liquid.

For a full understanding of the invention and the merits thereof, and to acquire a knowledge of the details of construction, reference is to be had to the following description and accompanying drawing, 1n which:

Figure 1 is a partial vertical section of a bottle showing our improved valve arrangement; Fig. 2 is a view of the valves detached and before their insertion into the bottle; and, Fig. 3 is a section on the line 3--3 of Fig. 1.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.

Referring to these figures, 2 designates the body of the bottle which may be of any suitable or desired form. Above the body, the neck of the bottle is constructed in a slightly conical formation, as at 3, so as to form a seat 4 normally occupied by a hollow valve 5. Above the seat 4, the neck is expanded, as at 6, so that the diameter' of this expanded portion is greater than the diameter of the valve 5. Above the expanded portion 6, the neck is again contracted, as at 7, and is there provided with inwardly projecting ribs 8, the channels between said ribs providing for the passa e of liquid when the bottle is inverted and t e valve 5 has rolled Specification of Letters Patent.

.10 so as to permit the valve to easily move from its seat when the bottle is inverted. Above the expanded or globular portion 7, the neck is again contracted as at 12, and on its interior is provided with inwardly extending ribs 13 the spaces between which form channels for the passage of liquid when the bottle is inverted and the valve 10 has rolled down to the lowest end of the globular portion 11.

111 designates a stopper of any suitable character which fits in the mouth of the bottle.

In order to initially fill the bottle, the valves 5 and 10 are connected by a very fine and flexible wire 15 which may be attached to the valve 5 in any suitable manner, as by wax. This wire is preferably slightly corrugated and passes through an opening in the valve 10. The object of this corrugation is to frietionally hold the ball valve 10 upon the wire in its proper location. Vhenit is desired to initially fill the bottle, the wire 15 is drawn upward so that the balls 10 and 5 are lifted from their seats 9 and 11. Liquid can then be introduced into the mouth of the bottle, and will fill the body thereof. The wire is then drawn'outward, breaking its engagement with the valve 5 and being pulled through the valve 9, thus leaving the two valves independent of each other a nd capable of resting upon their seats by gravity. It will be seen that the valves 5 and 10 will not interfere with the outward passage of the liquid when the bottle is inverted, but that they will prevent any introduction of liquid into the body of the bottle. Thus, `if the bottle is right side up, and it is attempted to introduce liquid, the valve 10 will be forced solidly against its seat, gravity itself acting to hold this valve to its seat, besides the actual force of the liquid being introduced. It is a common practice, however, to invert a bottle for the purpose of filling it, and for this purpose, the solid ball would be of no value. The hollow ball, however, has sutlicient buoyancy so that if the bottle be inverted, and liquid be introduced, the ball will float upward upon the surface of the. liquid until' it finds its seat 4,

thus closing,l the body of the bottle as effectually asdid the ball valve 10.

Vhile We have Shown what We regard as a preferable form of our invention, We do not Wish to be limited to the details, as the spirit of our, invention may be embodied in other forme, Without departingcg' therefrom.

Our device is simple, relatively cheap and entirely effective for the purpose for Which it-Avasy devised, L f

Having 'thuS ,described kthe invention, what is claimed as ,new is:-f-d

The combination with a .bottle having a neck provided with spaced superposed enlargementS constituting valve-seats, upper and lower valves normally engaging said seats, the upper valve being provided with a vertically disposed Wire receiving pasgsage, and a valve unseating member formed tions thereof frictionally engaging the walls of said passage, and a linger-piece secured to the free end of the valve unseating mem- *ber for simultaneously lii'ting both valves 'from their seats.'r`v c Y In testimonyxvhereof We afiix our signatures in presence of two Witnesses.- v
